SOLDERlNG-TWEEZERS.

SPECIFICATIONformingpart of Letters Patent No. 243,629, dated June 28, 1881.

' Application filed May 17, 1881. (No model.)

To all whom 1t may concern:

Be it known that I, LUCIOUS H. SANDERSON, a citizen of the United States of America, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Soldering-Tweezers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to soldering-tweezers for watch-makers and jewelers use, and for other purposes. The object is to construct a tool with which to clamp and hold smallarticles that are difficult to manipulate, and this is attained by means of spring-jaws actuated by the hand of the workman and a sliding device moved by the thumb, and so shaped and applied in connection with the jaws of the tool that the tweezers may be opened and closed at the will of the operator.

My invention therefore consists in a soldering-tweezers made with three holding jaws or arms, and formed out of one or more pieces of spring metal.

My invention further consists in a soldertweezers made of elastic metal and formed out of one or more pieces, in combination with a sliding clamp, whereby two of the holdingjaws or arms are opened or closed by the movement of the sliding clamp.

My invention also consists in the novel construction and combination of the parts, as will be hereinaftermore fully described and specifically claimed. I

In the annexed drawings, Figure l represents a perspective view of my improved soldering-tweezers. Fig. 2 represents the tool divested of the sliding clamp. Fig. 3 is a plan view of a blank, showing the outline of the sliding clamp; and Fig. 4 is a perspective view of the sliding clamp.

The letter A represents the wire frame of the tweezers, which may be constructed substantially in the following manner: I take a piece of wire, of sufficient strength and size and of the desired length to answer the purposes of the tool, and be the center until the parts as shown at a. desiied, according to th wires are struck down the prongs, as shown at and then again bent up At such nd it sharp around in are brought together, distance as may be e size of the tool, the

at right angles with Z) in the drawings, in a line with the shown at 0.

At this part they are bent in circular shape, forming the spring, and are carried together until about opposite the twist in the other arm of the tool when they are again twisted together for a short distance and clipped off to correspond W ith the length of the completed arms a a of the tool, after which they are spread, as shown at d in the drawings, in order to give a them. After being thus springing tension to spread apart they are bent down so as to form a swell of the form substantially as shown at c in the drawings,

and again spread apart and then bent toward 7 each other, forming another swell, :and carried toward each other until the points come together. plication The frame is now ready for the apof the sliding clamp.

The blank of this clamp is shown in Fig. 3, and the dotted lines indicate the outlines of the plate, which is put in shape by strik the plate on ing down the ends of the cross-lines, and the thumbrest being struck up, as shown in Fig. 1 of the drawings. Arepresentation of this clamp complete is shown in Fig. 4 of the drawings, and

it is applied to the tweezers by inserting the ends of the single prongs orjaws a a in the holes f and carrying the plate back over the wires, with the double arm a of the tweezers 0 underneath. The end of the arm a is brought up through the slot 9 and the plate carried back until the step of the double arm a comes into the slotg. The single prongs a a may now be shaped at their points to suit the op- 5 erator, and the double prong or arm a, after being united by solder at the end for a distance, can then be sh short aped as desired.

When it is desired to use the tool as a twopressure upon the handle ac- I00 and when desired to 001 the sliding clamp prong tweezers complishes the purpose, use it as a three-prong t is brought into requisition. By pressing it forward. with the thumb the effect of the inclines of the swells in the arms a a, as they pass through the plate, is to open the single jaws at the point, and by pressing the handle the other jaw, a is also thrown from the points of the others, and thus all are spread or opened. By releasing the pressure on the handle and drawing back the sliding plate the tool is closed at the points. The bent portion 1) forms a forefinger-rest for the hand of the operator.

It is obvious that the frame of the tool, as shown in Fig. 2 of the drawings, can be made of a single piece of wire.

What 1 claim as my invention, and desire to secure by Letters Patent, is-- 1. A soldering-tweezers having three arms or jaws formed of a bent piece or pieces of wire, substantially as described.
